consider the equation _. determine the steepness in the line between x=1 and x=2.
Answers
Answer:
2/3
Step-by-step explanation:
Firstly we get the y value at both x points
At x = 1
y = 2/3 + 1/2 = (4 + 3)/6 = 7/6
At x = 2
y = 4/3 + 1/2 = (8 + 3)/6 = 11/6
The slope formula is
m = (change in y)/change in x
The slope is thus;
(11/6-7/6)/(2-1) = 4/6 = 2/3

If a movie trailer offends 45 people in a theater, and then the feature movie disturbs 25 more people every scene the villain appears in, which of the following equations expresses the number of people offended or disturbed after "x" villain scenes in the movie? * A. y = 45 B. y = 25 C. y = 70x D.y = 25x + 45
Answers
Answer:
D. y = 25x + 45
Step-by-step explanation:
If it has already offended 45 people, that is our b. Now, we substitute 25 for m because it disturbs 25 more people per villain scene.

Answer:
x=145
Step-by-step explanation:
There are two ways to solve:
-Vertical angles Theorem states that opposite angles are congruent, so x=145 degrees.
-Sameside angles are supplementary so:
35+x=180
Subtract 35 from both sides:
x=145
Solve the system using elimination,
2x - 3y = - 19
7x + 7y = 21
Answers
Answer:
x = -2
y = 5
Step-by-step explanation:
2x - 3y = -19 ---------------------------(I)
7x+ 7y = 21 -----------------------------(II)
Multiply equation (I) by 7 and equation (II) by 3.Then add and so y will be eliminated and you will get the value of x
(I)*7 14x - 21y = - 133
(II)* 3 21x + 21y = 63 {Now add}
35x = -70
x = -70/35
x = - 2
Plug in x = - 2 in equation (I)
2*(-2) - 3y = -19
-4 - 3y = -19
-3y = -19 + 4
-3y = -15
y = -15/-3
y = 5

Nicole says she would multiply the first equation by 3 and add the two equations together to eliminate the x's. Michael says he would multiply the first equation by 2 and add the two equations to eliminate the y's.
Who is correct? and explain why.
Answers
Answer:
Nicole is correct
Step-by-step explanation:
by multiplying the first equation by 3 it becomes:
3x + 6y =21
this can cancel the -3x in the second equation when adding them together
Answer:
Nicole is correct, since when she multiplied by 3, she cleared the x's, since one x was already negative, and the other one was positive. Michael is incorrect since when he multiplied by 2, he didn't realize that both y's were positive, so they didn't clear.
Step-by-step explanation:
Let's see what will happen if we do what Nicole says:
x+2y=7
-3x+4y=9
multiply the first equation by 3 on both sides
3(x+2y)=7(3)
3x+6y=21
-3x+4y=9
now let's add them.
10y=30
We can see that the x's are cleared, since one x is positive and the other is negative.
Now let's try what Michael says.
x+2y=7
-3x+4y=9
multiply first equation by 2
2(x+2y)=7
2x+4y=7
-3x+4y=9
now let's add
-x+8y=16
the y's aren't eliminated, since both of them are positive.
Nicole is correct, since one x is positive and another was negative, and when opposite numbers are added together, they cancel out and equal zero.
Hope this helps!

A rectangle has a length of (2x-7) and a width of (x+5) perimeter
Answers
Answer:
6x - 4
Step-by-step explanation:
Perimeter is equal to double the length plus double the width, and if you use this to find perimeter, you would get that the perimeter = 2(2x-7)+2(x+5), which simplifies to 4x - 14 + 2x + 10, which simplifies to 6x - 4. That means that the rectangle's perimeter is 6x-4.

What is an arithmetic sequence?The sequence in which every next number is the addition of the constant quantity in the series is termed the arithmetic progression.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Will give brainliest!!! The MTC Theater holds 250 people, and last night’s performance sold out! Students under the age of 16 paid $2.50 per ticket, while everyone else paid $4.00 per ticket. Last night’s show brought in $910.
Write a system to represent the given equations.
How many adult tickets were sold?
How many under the age of 16 tickets sold
Answers
Step-by-step explanation:
Let the no. of adult tickets sold be 'a'
Let the no. of children tickets sold be 'c'
Total tickets sold = 250
Cost of 1 children ticket = $2.5
Cost of 1 adult ticket = $4
Total money collected= $910
Given that,
a + c = 250
a = 250 - c
4a + 2.5c = 910
Substitute a value
4(250 - c) + 2.5c = 910
1000 - 4c + 2.5c = 910
1000 - 1.5c = 910
-1. 5c = -90
1.5c = 90
c = 90/1.5
c = 60
a + c = 250
a + 60 = 250
a = 190
